As Republicans continue to question whether or not they should show support for presidential nominee Donald Trump, a sitting Republican congressman recently endorsed Democratic nominee Hillary Clinton.

Republican Rep. Richard Hanna of New York announced earlier this week that he will cross the party line and endorse Clinton. Hanna made the announcement through an op-ed he wrote for Syracuse.com. In it he echoes President Obama’s description of “unfit” by saying, “He is unfit to serve our party and cannot lead this country.”

Earlier this week President Obama urged Republican party leaders to withdraw their endorsements of the Republican nominee, Donald Trump. While speaking with the leaders, the president used the words “unfit to serve”, seeing Hanna’s op-ed mirroring the same sentiment shows that there is discourse on both sides of the party lines with Trump being a presidential hopeful. Ted Cruz, who ran against Trump before suspending his campaign in May, shocked many at the Republican National Convention when he said, “Vote with your conscience, vote for candidates up and down the ticket who you trust to defend our freedom and to be faithful to the Constitution.”

A sitting president has not openly criticized or critiqued a presidential hopeful since former President Harry S. Truman criticized Dwight D. Eisenhower in 1952, the Republican nominee. Eisenhower won the election against Adlai Stevenson.

Hanna did not write the piece completely bashing Trump and his policies and actions, but instead talks about why he will be voting for Clinton. One reason being because he is “a good American who loves his country”.

Hanna also wrote that he does disagree with Clinton on many of her policies and has been actively against Trump since March. He has served his home state since 2011 in the 22nd and 24th districts of upstate New York.
